I’ve got an OCZ Vertex3 MaxIO SSD as the main drive in my MacBook Pro. Now there is a firmware upgrade available from OCZ. As with many other vendors these kind of updates are only supported on Windows or Linux (at least), but not directly on a MacOS X. So what now?
I found a fairly easy way to do the upgrade. OCZ provides a Linux based update tool that downloads the actual firmware on demand from their website. So you need a computer that can run Linux, has internet connectivity and the drive accessible via a controller that allows the update.
Of course you can’t update the firmware of the drive you’ve booted from. So I just took a Ubuntu Linux Live CD and booted my MacBookPro (press C during boot) from the CD. From Linux I downloaded the firmware update pack from the OCZ website and ran in it a terminal.
This worked like charm. Hard disk was recognized, appropriate firmware update downloaded and disk updated. Done. No need to put your hard drive in another computer that runs the support OS or any other fiddling.
